Filed under Paper Guide. The standard office copy paper weight is most commonly called â20 lb. bondâ. Standard office copy paper weighs approximately 10.0 lbs per 1000 sheets. When people talk about âoffice copy paperâ, theyâre referring to the types of paper that most people use for their printers and photocopiers at home/work.
Paper may be between 0.07 and 0.18 millimetres (0.0028 and 0.0071 in) thick. Paper is often characterized by weight. In the United States, the weight assigned to a paper is the weight of a ream, 500 sheets, of varying basic sizes, before the paper is cut into the size it is sold to end customers. For example, a ream of 20 lb, 8.5 in Ã 11 in (216 mm Ã 279 mm) paper weighs 5 pounds, because it has been cut from a larger sheet into four pieces. In the United States, printing paper is generally 20 lb, 24 lb, or 32 lb at most.
